ABSTRACT:
A belt-type conveyor with two sections at a variable angle to each other and with a continuous belt that travels at each end over at least one deflection roller, at least one of which is driven and at least one of which can be shifted at an angle to its axis of rotation. The sections of belt associated with each conveyor section are accommodated in two channels that are positioned at a variable angle originating at an axis of articulation paralleling the axes of rotation of the deflection rollers and that have walls at each side of the belt extending above its upper strand, and is deflected around guide rollers in the vicinity of the axis of articulation between the conveyor sections. The axis of articulation between the adjustable-angle channels is on the side facing away from the level of the lower strand of the belt and away from the level of the upper strand. The walls of the two adjacent channels overlap throughout the range of angles between the two conveyor section. The axis of at least one deflection roller rests resiliently along the belt on structures that have at least approximately the same resilience over the whole range of angles between the conveyor sections.
